Edit: 35 Qvic flagged chars ( about one third were boxed ) took her down. She can't be slowed ( if I remember correctly ), has tons of HP, debuffs and AEs like crazy.
I tanked right in front of her but she just kept summoning me to under her belly ( Call of zero ). ( Where I got the message saying that I couldn't see my target. )
She dropped Fabled Silver Girdle of Stability, Silver Girdle of Stability, Lendiniara's Talisman, Ring of Relkententinar and Velium Maul of Superiority.
